A skin-like biomedical technology that uses a mesh of conducting nanowires and a thin layer of elastic polymer might bring new electronic bandages that monitor biosignals for medical applications and provide therapeutic stimulation ...

In a breakthrough for future optical-electronic hybrid computers, scientists at EPFL have developed an ultrafast technique that can track light and electrons as they travel through a nanostructured surface.

Next-generation anodes for lithium ion batteries will probably no longer be made of graphite. Silicon, which is a related material, can provide a much higher capacity than graphite, but its crystallinity poses problems. In ...

Sagrario Domínguez-Fernández, a telecommunications engineer, has managed to increase light absorption in silicon by means of nanostructures etched onto photovoltaic cells. This increases the efficiency obtained in these ...

A new technology that is easy to manufacture and uses commercially available materials makes it possible to continuously remove oils and other pollutants from water, representing a potential tool for environmental cleanup.

Physicists at the Technical University of Munich (TUM) have developed a nanolaser, a thousand times thinner than a human hair. Thanks to an ingenious process, the nanowire lasers grow right on a silicon chip, making it possible ...

By tailoring the interface between the two sections of a solar cell, A*STAR researchers have produced a high-performance solar cell from the abundant and cheap materials of copper (II) oxide and silicon.

More than 80 percent of microbial infections in the human body are caused by a build-up of bacteria, according to the National Institutes of Health. Bacteria cells gain a foothold in the body by accumulating and forming into ...

Spherical gold particles are able to 'drill' a nano-diameter tunnel in ceramic material when heated. This is an easy and attractive way to equip chips with nanopores for DNA analysis, for example. Nanotechnologists of the ...
